3 Claims.

This invention relates to sacks for vacuum cleaners and has for theprimary object the provision of a device of the above stated characterwhich will be inexpensive to manufacture so that 5 after once filledwith dirt from a vacuum cleaner it may be discarded and anothersubstituted therefore and is so constructed that it will effectivelytrap dirt, dust and the like and still permit air to escape during itsuse on a vacuum cleaner.

With these and other objects in view this invention consists in certainnovel features of construction, combination and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 isa perspective View illustrating a sack constructed in accordance with myinvention and showing the same applied to a vacuum cleaner.

Figure 2 is a plan view illustrating the sack. Figure 3 is a sectionalview taken on the line 3-3 of Figure 2.

Figure 4 is an enlarged fragmentary sectional view illustrating themouth of the sack.

Referring in detail to the drawing, the numeral 1 indicates a sackespecially adaptable for vacuum cleaners and is so constructed that itmay be conveniently applied to any vacuum cleaner now in use.

The sack 1 is preferably of paddle shape providing a restricted neck 2adapted for application to the vacuum cleaner. The sack includes spacedwalls 3 constructed of paper or any other material suitable for thepurpose.

The

walls 3 are connected in spaced relation by a foraminous binding strip 4preferably of a suitable fabric.

A spacer or filler 5 is arranged between the walls 3 and against thestrip 4 and has embedded therein a reinforcing element 6 for the purposeof retaining the sack in paddle shape with the filler held against thebinding strip 4. The filler is preferably constructed from cotton whichwill permit air to pass therethrough when under pressure and willcollect dust, dirt and other foreign matter.

dirt and other foreign matter.

Thus it will be seen that an inexpensive sack has been provided which isadaptable to vacuum cleaners and will successfully trap dirt and otherforeign matter therein still permitting the escape of the air from thevacuum cleaner. A sack of this character after once filled with dirt andother foreign matter can be discarded and another substituted on thevacuum cleaner in lieu thereof.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in construction,combination and arrangement of parts may be made without departing fromthe spirit and scope of my invention, as claimed.

Having described the invention, I claim:

1. A sack for vacuum cleaners comprising a flat container having athroat for connection to a vacuum cleaner and including spaced wallsmade of paper and connected by foraminous material, means for retainingthe walls in spaced relation and engaging the foraininous material toprevent the passage of foreign matter through said foraminous material,said walls having openings, and means closing said openings to permitescape of air through the openings and to prevent the pas- 80 sage offoreign matter through said openings.

2. A sack for vacuum cleaners comprising a container having a throat forconnection to a vacuum cleaner and including spaced walls havingopenings, foraminous material connecting said walls, a filler betweensaid walls and engaging said foraminous material, a reinforcement forthe filler and air straining means overlying the openings.

3. A sack for vacuum cleaners comprising a container having a throat forconnection to a vacuum cleaner and including spaced walls havingopenings, foraminous material connecting said walls, a filler betweensaid walls and engaging said foraminous material, a reinforcement forthe filler, foraininous material secured to said walls over the openingsand arranged upon opposite faces of each wall, straining materialsecured to said Walls over the openings by the last-named foraminousmaterial.
